I ran my bin through me7sum and me7check, both agree on my file being ok. Is this possible after I add in a new MAF linearisation? Last changes I made in the area resulted in checksum fixes, so I found it weird that it will not see any errors now.
Call me paranoide but I would love to have this bin checked by a 2nd person :-) Thanks!
--------------------------------------------------
I split the bin again and now all is ok!

*** Found 41 checksums in 018AAmafsplit.bin

Attempting to output corrected firmware file 'aamaf_fixed.bin'
Ý Opening 'aamaf_fixed.bin' file for writing
Ý Writing to file
Ý Validating size correct 524288=524288
Ý All OK, closing file

*** DONE! 4/4 error(s) corrected in 018AAmafsplit.bin! ***

Haha yes thanks, I got the same. I am more curious if me7check misses something here, or is it plausible a file does not need checksum correction after 512 row map is changed??

Oh, just sprung to mind:
This file is original 1024kb, but it comes from a 400BB chip. I cut it in half because me7sum will not correct the full 1024kb file. me7check does recognize this to be a 512kb file. I add the uncut bin as well. Last time I split the bin I was able to correct the cs, but now it doesnt find any errors... did I get the wrong end from my split maybe?  Shocked
